Abstract



The phytochemical contents and medicinal values of Dacryodes edulis and Raphia hookeri exudates were investigated. Phytochemical screening of the plant showed that they contain the presence of bioactive compounds comprising saponins (2.08-3.98mg 100g-1), alkaloids (0.28-0.49 mg 100g-1), tannins (0.47-0.72 mg 100g-1), flavonoids (0.26-0.39 mg 100g-1), and phenolic compounds (0.01-0.05 mg 100g-1). The carbohydrates, lipids and protein content were 77.42-78.90%, 2.02-4.185% and 16.63-18.38% respectively. The exudates are a good source of water soluble vitamins; ascorbic acid (7.04-26.40 mg 100g-1), niacin (3.12-4.00 mg 100g-1), riboflavin (0.14-0.54 mg 100g-1) and thiamine (0.15-0.22 mg 100g-1),). Both plants exudates are good sources of minerals such as Ca, Mg, P, Fe, Zn, Cu and Mn while Cr and Co were trace. These results indicate that exudates can be potential sources of feedstock for the pharmaceutical industry.
